New research gives a detailed look at the extent to which receding glaciers in Alaska and elsewhere in the Northern Hemisphere are creating new coastline and how that newly exposed terrain is behaving.
With the Great Mussel Die-Off, Scientists Scramble for Answers
Throughout his professional life, U.S. Forest Service researcher Wendell Haag has studied freshwater mussels in their hotspot of biological diversity, which extends across a vast swath of the southeastern United States.
Mammoth genetic diversity throughout the last million years
A new genomic study has uncovered long-lost genetic diversity in mammoth lineages spanning over a million years, providing new insights into the evolutionary history of these animals.
Mediterranean hunter gatherers navigated long-distance sea journeys well before the first farmers
Evidence shows that hunter-gatherers were crossing at least 100 kilometers (km) of open water to reach the Mediterranean island of Malta 8,500 years ago, a thousand years before the arrival of the first farmers.
Starch-based microplastics could cause health risks in mice
Wear and tear on plastic products releases small to nearly invisible plastic particles, which could impact people's health when consumed or inhaled. To make these particles biodegradable, researchers created plastics from plant starch instead of petroleum. An initial study shows how animals consuming particles from this alternative material developed health...
Life recovered rapidly at site of dino-killing asteroid: A hydrothermal system may have helped
About 66 million years ago, an asteroid slammed into the planet, wiping out all non-avian dinosaurs and about 70% of all marine species. But the crater it left behind in the Gulf of Mexico was a literal hotbed for life enriching the overlying ocean for at least 700,000 years, according...
What’s on the menu for Ryukyu’s minute mammals?
Japan's Ryukyu Islands, which includes Okinawa, are the exclusive home to two rare mammals, the Amami rabbit and Ryukyu long-furred rat. These animals are hard to observe, but conservationists wish to find out specific details about their diets. So researchers inspected the teeth from deceased specimens to find out what...
New research finds fluorescence in feathers of long-eared owls
Researchers report their discovery of fluorescent pigments in the feathers of Long-eared Owls, that can only be seen by humans with the help of ultraviolet light.
Powerful Methane Emissions from Lake Siljan Puzzle Researchers
Unexpectedly strong methane emissions have been detected at several locations in Lake Siljan, Sweden, according to a new study from Chalmers University of Technology.
Study: Burning Heavy Fuel Oil With Scrubbers is the Best Available Option for Bulk Maritime Shipping
When the International Maritime Organization enacted a mandatory cap on the sulfur content of marine fuels in 2020, with an eye toward reducing harmful environmental and health impacts, it left shipping companies with three main options.
